Ulnar morphology in Sahelanthropus tchadensis, what it tells us on the locomotor repertoire of the last common ancestor of humans and chimpanzees (LCA)

The positional repertoire that foreshadowed the emergence of hominin bipedalism is highly debated, the last common ancestor (LCA) being alternatively described as a semiterrestrial vertical climber and knuckle-walker ape, or described as a mostly arboreal ape mainly engaged in non stereotypic quadru...

Description
Summary:The positional repertoire that foreshadowed the emergence of hominin bipedalism is highly debated, the last common ancestor (LCA) being alternatively described as a semiterrestrial vertical climber and knuckle-walker ape, or described as a mostly arboreal ape mainly engaged in non stereotypic quadrupedal and bipedal behaviours. Studying forearm bones, which play a significant role in those possible LCA’s locomotor behaviors, should help to better appraise earliest hominin locomotor repertoire...
